A three-vehicle collision on the inner loop of Interstate 695 prior to Exit 16 (Interstate 70) in Baltimore County hampered traffic toward the end of the morning rush hour, according to the state Department of Education.

The crash closed one of four inner loop traffic lanes and one of two inner loop shoulders at 9:15 a.m., DOT said.

Bad roads and congestion cost Baltimore-area drivers nearly $1,800 a year in lost time, vehicle repairs and wasted gas, according to a study released Thursday by TRIP, a national transportation industry group.

All northbound traffic on Interstate 895 in Baltimore City has been closed due to a two-vehicle collision at the Harbor Tunnel at 8:49 a.m. on Thursday, according to the state Department of Transportation.
